JAMES RYDER LATHAM, OF NEW YORK, N. Y.

, NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 595,487, dated December 14, 1897.

' Application filed September 2,1896. Serial No. 604,679. (No model.)

To ctZZ whom it may concern.-

Be it known that I, JAMES RYDER LATHAM, of the city and county of New York, in the State of New York, have invented a new and useful Improvement in Non-Refillable Bottles, of which the following is a specification.

The object of my invention is to provide a non-refillable bottle which will be very simple in construction and arrangement and in which the bottle is effectually guarded against refilling.

A further obj ectis to provide a device which will keep the exit from the bottle automatically closed, in whatever position the bottle is turned, as long as the mouth of the same is not depressed below the body of the bottle.

A practical embodiment of my invention is represented in the accompanying drawings, in which v Figure 1 represents a vertical central section through the upper portion and neck of a bottle with my improved device therein: Fig. 2 is a similar view of the same in a position to pour out the contents of the bottle. Fig. 3 is a transverse section on the line 3 3 of Fig. 1. Fig. 4 is a vertical central section through the upper portion and neck of a bottle, showing a modified form of gravity closing device.

Fig. 5 is a transverse section through the neck of the bottle on the line 5 5 of Fig. 4; and Fig. 6 is a vertical central section through the upper portion and neck of a bottle, showing a second modified form of gravity closing device. I

The body of the bottle is denoted by A and its neck byB. An exit-tube 0, through which the contents of the bottle are allowed to escape, is secured within the neck of the bottle, in the present instance by means of a seal or cork D.

The gravity closing device shown in Figs. 1, 2, and 3 consists of a loose weighted collar E, which is fitted to the end of the exittube 0 in such a manner that the collar will rotate freely on the said tube, and a flap, valve or door 6, hinged to the collar, so as to normally close the end of the said collar in Whatever position the bottle is turned as long as it is not inverted. The way I have weighted the collar E is to increase the size of the said collar on one side, and I then hinge'the valve 6 at a point opposite the weighted portion of the collar. The collar E is held in any suitable manner against a sliding movement longitudinally along the tube 0. In the present instance I have shown a gasket or ring 6 inserted within the collar E and closely fitted to the interior of the said collar, the end of the tube 0 being shown as provided with a flange 0 around its month, which flange bears against a shoulder in the collar E.

In the form shown in Fig. 4 the gravity closing device for the end of the exit-tube 0 consists of a suitable weighted valve E, which valve has a loose connection with the end of the exit-tube C, so that the said valve may be rotated freely on the said tube. tThe end wall of the said valve E serves to close the mouth of the tube 0, and the said tube C is provided with a circumferential groove 0', into which a projection e from the valve E projects, thereby forming a hinge for the said valve. The said valve E is provided with a port or slot 6 through its weighted or lower portion, through which the liquid which passes through the tube 0 escapes when the mouth of the bottle is depressed below the body of the same.

The gravity closing device shown in Fig. 6 consists of a weighted valve E which closes the mouth of the tube 0, and is further provided with a projection 6 which runs freely Y in the circumferential groove 0 in the tube 0.

The means which I have employed forpreventing tampering with the gravity closing device is a shield G, which is secured in position in the neck of the bottle above the gravity device, the said shield Gbeing preferably solid. The liquid from within the bottle is allowed to escape by the edge of the shield G through suitable channels b, formed in the neck B.

A suitable cork or stopper H may be inserted into the mouth of the neck above the shield G.

The gravity closing device as above described will be closed at all times except when the bottle is tilted for pouring the liquid out, it making no difference how the bottle may be rotated while pouring or before pouring, the weight of the valve being sufficient to keep the hinge of the same always at the upper portion of the exit-tube. The

weighted valve ispreferably so constructed that communication with the interior of the bottle will not be opened until the neck of the bottle is depressed quite a distance below a horizontal position.

It will be further seen that the device as above described has a very few parts and maybe very readily placed in position in the bottle and with but little expense.

It is evident that slight changes might be resorted to in the construction and arrangement of the several parts without departing from the spirit and scope of my invention. Hence I do not wish to limit myself strictly to the structure herein set forth, but

- \Vhat I claim is 1. The combination with the neck of a bottle, of an exit-tube secured therein, the said exit-tube having a circumferential guide thereon, and a weighted gravity closing device engaging the said guide on the tube and having a free rotary movement around the same, the said gravity closing device being located in position to automatically close the end of said tube except when the bottle is inverted, substantially as set forth.
